Question

In java, there is a constant for the max value of Long.
Such as:

long minBillId = Long.MAX_VALUE

Is there a constant for the max value of long or int in Obj-C?

Answer 1

If you import limits.h
you can call LONG_MAX

For reference this site shows how to get the max for all types as such:

#import <limits.h>
 // ...
NSLog(@"CHAR_MIN:   %c",   CHAR_MIN);
NSLog(@"CHAR_MAX:   %c",   CHAR_MAX);
NSLog(@"SHRT_MIN:   %hi",  SHRT_MIN);    // signed short int  
NSLog(@"SHRT_MAX:   %hi",  SHRT_MAX);
NSLog(@"INT_MIN:    %i",   INT_MIN);
NSLog(@"INT_MAX:    %i",   INT_MAX);
NSLog(@"LONG_MIN:   %li",  LONG_MIN);    // signed long int
NSLog(@"LONG_MAX:   %li",  LONG_MAX);
NSLog(@"ULONG_MIN not defined, it's always zero: %lu", 0);  
NSLog(@"ULONG_MAX:  %lu",  ULONG_MAX);   // unsigned long int
NSLog(@"LLONG_MIN:  %lli", LLONG_MIN);   // signed long long int
NSLog(@"LLONG_MAX:  %lli", LLONG_MAX);
NSLog(@"ULLONG_MIN not defined, it's always zero: %llu", 0);  
NSLog(@"ULLONG_MAX: %llu", ULLONG_MAX);  // unsigned long long int
